In a list of codes for grounding standards, which option corresponds to the National Electrical Safety Code?

• A. National Electrical Code
• B. International Safety Code
• C. National Electrical Safety Code
• D. American Safety Standard

Answer: (C)

Grounding standards for electrical systems are governed by specific national codes. The National Electrical Safety Code is the standard that governs safety for the construction and operation of electric supply and communication lines, including how grounding and bonding should be done to protect the public and workers. It is the code referenced for outdoor distribution grounding practices, not the building-focused National Electrical Code, which addresses wiring inside structures. The other options don’t match the formal designation used in this context: the National Electrical Code is about building wiring, International Safety Code isn’t a formal U.S. standard name, and American Safety Standard is generic. So the National Electrical Safety Code is the correct choice.
